Description

Technical Field

[0001] The present invention relates to an electric compressor.

Background Art

[0002] An electric compressor includes a compression part, an electric motor, an inverter, and a housing. The compression part compresses a fluid. The electric motor drives the compression part. The inverter drives the electric motor. The housing houses the compression part, the electric motor, and the inverter. The housing is made of metal.

[0003] By the way, in such an electric compressor, vibration and noise are generated when the compression part is driven, or vibration and noise are generated when the electric motor is driven. Thus, when vibration and noise are generated from inside the housing, the housing vibrates. Then, radiated sound is generated from the housing. Therefore, conventionally, it has been considered to cover the outer surface of the housing with a soundproof cover as in Patent Document 1. The soundproof cover absorbs the radiated sound from the housing. As a result, the noise of the electric compressor is suppressed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in such an electric compressor, a nameplate may be attached to the outer surface of the housing. The nameplate includes predetermined information such as information on the product number of the electric compressor, information on the lot number at the time of manufacture of the electric compressor, and information on precautions for use of the electric compressor. However, when the outer surface of the housing is covered with a soundproof cover as in Patent Document 1, the nameplate cannot be confirmed from the outside of the electric compressor.

[0006] Therefore, for example, it is conceivable to attach a nameplate to the outer surface of the soundproof cover. However, for example, when the soundproof cover is formed of a resin material such as a urethane material, the nameplate cannot be properly adhered to the soundproof cover unless an adhesive corresponding to the resin material is used. That is, if the soundproof cover is formed of a resin material, even if the nameplate is attached to the outer surface of the soundproof cover, the attachability of the nameplate to the soundproof cover becomes unstable.

[0007] Further, in an electric compressor, when the outer surface of the housing is covered with a soundproof cover, the heat dissipation of the housing decreases. Therefore, improvement of the heat dissipation of the housing is desired.

Means for Solving the Problems

[0008] The electric compressor that solves the above problems includes a compression unit that compresses the fluid inhaled from the suction chamber and discharges it to the discharge chamber, an electric motor that drives the compression unit, an inverter that drives the electric motor, a housing in which the suction chamber and the discharge chamber are formed and that houses the compression unit, the electric motor, and the inverter, a soundproof cover that covers the outer surface of the housing, and a nameplate that includes predetermined information. The housing has an inverter housing portion that houses the inverter and a discharge portion that forms the discharge chamber. When a portion of the outer surface corresponding to the inverter housing portion is defined as a first outer surface and a portion of the outer surface corresponding to the discharge portion is defined as a second outer surface, the nameplate is provided on at least one of the first outer surface and the second outer surface, and the soundproof cover has a window for viewing the nameplate at a portion corresponding to the nameplate.

[0009] According to the above configuration, the nameplate is provided on at least one of the first outer surface and the second outer surface of the outer surface of the housing. Therefore, for example, compared with the case of attaching a nameplate to a soundproof cover generally formed of a resin material or the like, the nameplate can be stably attached. Thus, the reliability of attaching the nameplate is improved.

[0010] Further, the soundproof cover has a window for viewing the nameplate at a portion corresponding to the nameplate. Therefore, the nameplate can be confirmed through the window from the outside of the electric compressor. Further, the window of the soundproof cover is provided at a position corresponding to at least one of the inverter housing portion and the discharge portion. The temperature of the inverter housing portion tends to rise due to the heat generation of the electronic components, and the temperature of the discharge portion tends to rise due to the fluid compressed and discharged. For this reason, heat from at least one of the inverter housing portion and the discharge portion is radiated to the outside through the window. Thus, the heat dissipation of the housing is improved. Further, the inverter housing portion and the discharge portion are portions where the noise is small in the housing as compared with the portion that houses the compression portion and the electric motor in the housing. For this reason, even if a window is provided in the soundproof cover, the reduction in the noise reduction effect can be minimized. Therefore, while suppressing the reduction in the noise reduction effect, it is possible to improve the heat dissipation of the housing, confirm the nameplate from the outside, and improve the reliability of attaching the nameplate.

[0011] In the above electric compressor, the window may surround the nameplate. According to the above configuration, the entire nameplate can be visually observed through the window from the outside of the electric compressor. Thus, it is easy to appropriately confirm the predetermined information included in the nameplate.

[0012] In the above electric compressor, the window may have a shape along the outer edge of the nameplate. According to the above configuration, it is easy to realize a configuration in which the size of the window provided in the soundproof cover is not made larger than necessary. Thus, it is possible to make it difficult to reduce the noise reduction effect by the soundproof cover.

[0013] In the above electric compressor, the nameplate may be provided on the first outer surface. For example, when the nameplate is attached to the housing by an adhesive layer composed of an adhesive, if the temperature of the portion where the nameplate is provided is high, the adhesive layer deteriorates. For this reason, it is difficult to stably hold the adhesive layer. Generally, when comparing the inverter housing portion and the discharge portion, the temperature of the inverter housing portion is relatively lower than the temperature of the discharge portion.

[0014] In this regard, according to the above configuration, the nameplate is attached to a relatively low-temperature portion of the housing. Therefore, when the nameplate is adhered to the housing using the adhesive layer, the adhesive layer can be held relatively stably. Therefore, the reliability of attaching the nameplate can be further improved.

Effects of the Invention

[0015] According to the present invention, it is possible to suppress a decrease in the noise reduction effect, improve the heat dissipation performance of the housing, enable confirmation of the nameplate from the outside, and improve the reliability of attaching the nameplate.

Modes for Carrying Out the Invention

[0017] [First Embodiment] Hereinafter, a first embodiment in which an electric compressor is embodied will be described with reference to FIGS. 1 to 4. The electric compressor of the present embodiment is used, for example, in a vehicle air conditioner.

[0018] [Configuration of Electric Compressor] As shown in FIG. 1, the electric compressor 10 includes a housing 20, a compression portion 30, an electric motor 40, an inverter 50, a nameplate 60, and a soundproof cover 70.

[0019] The compression section 30 compresses the refrigerant as a fluid. The compression section 30 is of a scroll type composed of a fixed scroll and a movable scroll (not shown). The compression section 30 compresses the refrigerant inhaled into the housing 20 as the electric motor 40 is driven.

[0020] The electric motor 40 drives the compression section 30. The inverter 50 drives the electric motor 40. The housing 20 houses the compression section 30, the electric motor 40, and the inverter 50. The nameplate 60 is attached to the housing 20. The soundproof cover 70 covers the outer surface 20a of the housing 20.

[0021] <Configuration of the housing> The housing 20 is cylindrical. The housing 20 is made of metal. The housing 20 is, for example, made of aluminum. The direction in which the axis m of the housing 20 extends is defined as the axial direction A. The direction orthogonal to the axis m of the housing 20 is defined as the radial direction B. The housing 20 has a first component 21, a second component 22, and a third component 23.

[0022] The first component 21 has an end wall 21a and a peripheral wall 21b. The peripheral wall 21b is cylindrical. The peripheral wall 21b extends from the outer peripheral portion of the end wall 21a. The axis of the peripheral wall 21b coincides with the axis m of the housing 20. The peripheral wall 21b has an outer peripheral surface 21c. The compression section 30 and the electric motor 40 are housed in the first component 21.

[0023] An inhalation chamber S1 is formed inside the first component 21. The refrigerant to be compressed by the compression section 30 is inhaled into the inhalation chamber S1. The inhalation chamber S1 is a space surrounded by the end wall 21a and the peripheral wall 21b. The inhalation chamber S1 also serves as a motor chamber in which the electric motor 40 is housed.

[0024] The second component 22 has an end wall 22a and a peripheral wall 22b. The peripheral wall 22b is cylindrical. The peripheral wall 22b extends from the outer peripheral portion of the end wall 22a. The peripheral wall 22b has an outer peripheral surface 22c. The end wall 22a has an outer surface 22d. The outer surface 22d is continuous with the outer peripheral surface 22c.

[0025] The first component 21 and the second component 22 are connected in the axial direction A. The first component 21 and the second component 22 are fixed by bolts (not shown). The end portion of the peripheral wall 21b located on the side opposite to the end wall 21a abuts against the end portion of the peripheral wall 22b located on the side opposite to the end wall 22a in the axial direction A.

[0026] A discharge chamber S2 is formed inside the second component 22. The refrigerant compressed by the compression portion 30 is discharged into the discharge chamber S2. That is, the second component 22 is a discharge portion that forms the discharge chamber S2. An intake chamber S1 and a discharge chamber S2 are formed in the housing 20. The compression portion 30 compresses the refrigerant inhaled from the intake chamber S1 and discharges it into the discharge chamber S2.

[0027] The third component 23 is connected to the first component 21 in the axial direction A. The third component 23 is connected to the end wall 21a of the first component 21. The first component 21 and the third component 23 are fixed by bolts (not shown). The third component 23 has a shape in which a part thereof protrudes more than the first component 21 in the radial direction B. An inverter 50 is housed in the third component 23. The third component 23 is an inverter housing portion that houses the inverter 50.

[0028] The third component 23 has a first surface 23a, a second surface 23b, and a third surface 23c. The first surface 23a is in contact with the end wall 21a. The first surface 23a has an exposed surface 23d that is not in contact with the end wall 21a. The second surface 23b is a surface located on the side opposite to the first surface 23a in the axial direction A. The third surface 23c is a surface that connects the first surface 23a and the second surface 23b.

[0029] <The outer surface of the housing> The outer surface 20a of the housing 20 forms the outer shape of the electric compressor 10. The outer surface 20a includes outer peripheral surfaces 21c, 22c, an outer surface 22d, a second surface 23b, a third surface 23c, and an exposed surface 23d. That is, the outer surface 20a of the housing 20 is the surface that is externally exposed when not covered by the soundproof cover 70.

[0030] The second surface 23b, the third surface 23c, and the exposed surface 23d are the first outer surfaces that are portions of the outer surface 20a corresponding to the inverter housing portion. The outer peripheral surface 22c and the outer surface 22d are the second outer surfaces that are portions of the outer surface 20a corresponding to the discharge portion.

[0031] <Configuration of the nameplate> As shown in FIGS. 1 and 2, in the present embodiment, the nameplate 60 is a seal made of a flexible material having a rectangular shape. The nameplate 60 is adhered to the second surface 23b of the third component 23 via an adhesive layer 61 formed by an adhesive. The nameplate 60 is provided on the first outer surface of the portion of the outer surface 20a corresponding to the inverter housing portion.

[0032] As shown by the two-dot chain line in FIG. 2, the nameplate 60 contains predetermined information 62. The predetermined information 62 is described on the surface of the nameplate 60 opposite to the adhesive layer 61. The predetermined information 62 is, for example, the product number of the electric compressor 10, the lot number at the time of manufacture of the electric compressor 10, precautions for use of the electric compressor 10, and the like. The predetermined information 62 may be, for example, a QR code (registered trademark) that summarizes the above-described information.

[0033] <Configuration of the soundproof cover> The soundproof cover 70 is formed of, for example, a resin material that can be elastically deformed. The soundproof cover 70 is formed of, for example, a urethane material.

[0034] As shown in FIGS. 2 and 3, the soundproof cover 70 has a first cover 71 and a second cover 72. The first cover 71 and the second cover 72 each have a housing recess 70a along the outer shape of the housing 20.

[0035] The soundproof cover 70 has a through portion 73, and thus a through hole H73 is formed in the soundproof cover 70. That is, the through portion 73 is the surface that forms the through hole H73. The through hole H73 penetrates the soundproof cover 70. The through portion 73 and the through hole H73 are arranged so as to straddle the boundary between the first cover 71 and the second cover 72. The through hole H73 is provided at a position corresponding to the nameplate 60 in the soundproof cover 70.

[0036] The through portion 73 has a first notch surface 71a and a second notch surface 72a. The first notch surface 71a is formed in the first cover 71. The second notch surface 72a is formed in the second cover 72. The first notch surface 71a and the second notch surface 72a are continuous.

[0037] As shown in FIG. 4, the first notch surface 71a and the second notch surface 72a are separated from the nameplate 60 by a predetermined distance. The first notch surface 71a and the second notch surface 72a have a shape along the outer edge of the nameplate 60. That is, when the through portion 73 is viewed from the front in the thickness direction of the nameplate 60, it has a rectangular shape. The through portion 73 surrounds the nameplate 60. The through portion 73 has a shape along the outer edge of the nameplate 60. The predetermined information 62 of the nameplate 60 is entirely exposed from the through portion 73. That is, the through portion 73 is a window for viewing the nameplate 60 provided at a portion corresponding to the nameplate 60. The predetermined distance is set such that the size of the through portion 73 does not significantly reduce the noise reduction effect by the soundproof cover 70.

[0038] [Operation of this Embodiment] The operation of this embodiment will be described. In this embodiment, when the compression portion 30 and the electric motor 40 are driven, noise is generated through the housing 20. However, since the housing 20 is covered by the soundproof cover 70, the noise of the electric compressor 10 is reduced.

[0039] In addition, a nameplate 60 is provided on the second surface 23b of the outer surface 20a of the metal housing 20. Therefore, for example, compared with the case where the nameplate 60 is attached to the soundproof cover 70 formed of a resin material, the nameplate 60 is stably attached.

[0040] Further, the soundproof cover 70 has a through portion 73 at a portion corresponding to the nameplate 60. Therefore, an operator can confirm the nameplate 60 from the outside of the electric compressor 10 through the through portion 73. Further, the through portion 73 of the soundproof cover 70 is provided at a position corresponding to the third component 23 as an inverter housing portion. The temperature of the third component 23 is likely to rise due to heat generation of the electronic components, and the temperature of the second component 22 is likely to rise due to the refrigerant compressed and discharged. For this reason, the heat from the third component 23 is radiated to the outside through the through portion 73.

[0041] Further, the third component 23 is a portion where the noise is small in the housing 20 as compared with the portion that houses the compression portion 30 and the electric motor 40 in the housing 20. For this reason, even if the through portion 73 is provided in the soundproof cover 70, the reduction effect of the noise reduction effect is small.

[0042] [Effects of the present embodiment] The effects of the present embodiment will be described. (1-1) The through portion 73 is a portion that is likely to become relatively high temperature in the electric compressor 10 and is located at a position corresponding to a portion with low noise, and is arranged so that the nameplate 60 can be visually recognized. Therefore, while suppressing the reduction of the noise reduction effect, it is possible to improve the heat dissipation of the housing 20, confirm the nameplate 60 from the outside, and improve the reliability of the attachment of the nameplate 60.

[0043] (1-2) The through portion 73 surrounds the nameplate 60. The entire nameplate 60 can be visually observed from the outside of the electric compressor 10 through the through portion 73. Therefore, it is easy to appropriately confirm the predetermined information 62 included in the nameplate 60.

[0044] (1-3) The through-hole portion 73 has a shape along the outer edge of the nameplate 60. Therefore, it is easy to realize a configuration in which the size of the through-hole portion 73 provided in the soundproof cover 70 is not made larger than necessary. Thus, it is possible to make it difficult to reduce the noise reduction effect by the soundproof cover 70.

[0045] (1-4) When the nameplate 60 is attached to the housing 20 by the adhesive layer 61, if the temperature at the location where the nameplate 60 is provided is high, the adhesive layer 61 deteriorates. For this reason, it is difficult to stably hold the adhesive layer 61. Generally, when comparing the third component 23 and the second component 22, the temperature of the third component 23 is relatively lower than the temperature of the second component 22.

[0046] In the present embodiment, the nameplate 60 is attached to a portion of the housing 20 where the temperature is relatively low. Therefore, when the nameplate 60 is adhered to the housing 20 using the adhesive layer 61, the adhesive layer 61 can be held relatively stably. Thus, the reliability of attaching the nameplate 60 can be further improved.

[0047] [Second Embodiment] Hereinafter, a second embodiment in which an electric compressor is embodied will be described with reference to FIG. 5. The main difference between this embodiment and the first embodiment is that the attachment position of the nameplate is changed. This point will be described in detail, and the same components as those in the first embodiment will be denoted by the same reference numerals, and detailed description thereof will be omitted.

[0048] [Attachment Position of Nameplate and Configuration of Soundproof Cover] As shown in FIG. 5, the nameplate 60 is provided on the outer surface 22d of the second component 22. The nameplate 60 is provided on the second outer surface of the portion of the outer surface 20a corresponding to the discharge portion.

[0049] The second cover 72 has a through portion 74, and thus a through hole H74 is formed in the second cover 72 of the soundproof cover 70. That is, the through portion 74 is the surface that forms the through hole H74. The through hole H74 penetrates the soundproof cover 70. The through hole H74 is provided at a position corresponding to the nameplate 60 in the soundproof cover 70. The nameplate 60 is accommodated in the through hole H74.

[0050] The shape of the through portion 74 is the same as the shape of the through portion 73 described in the first embodiment. The through portion 74 is separated from the nameplate 60 by a predetermined interval. The through portion 74 has a shape along the outer edge of the nameplate 60. That is, when the through portion 74 is viewed from the front in the thickness direction of the nameplate 60, it has a rectangular shape. The through portion 74 surrounds the nameplate 60. That is, the through portion 74 is a window for viewing the nameplate 60 provided at a portion corresponding to the nameplate 60. Note that the predetermined interval is set such that the size of the through portion 74 does not significantly reduce the noise reduction effect by the soundproof cover 70.

[0051] [Operation of this embodiment] The operation of this embodiment will be described. The soundproof cover 70 has a through portion 74 that penetrates a portion corresponding to the nameplate 60. Therefore, the operator can confirm the nameplate 60 from the outside of the electric compressor 10 through the through portion 74. Further, the through portion 74 of the soundproof cover 70 is provided at a position corresponding to the second component 22 as the discharge portion. For this reason, the heat from the second component 22 is radiated to the outside through the through portion 74.

[0052] [Effect of this embodiment] According to this embodiment, the same effects as (1-1), (1-2), and (1-3) of the first embodiment can be obtained, and the following effects can also be obtained.

[0053] (2-1) In the discharge chamber S2, a high-temperature and high-pressure refrigerant is discharged from the compression unit 30. Therefore, the second component 22 is more likely to become hotter than the third component 23. However, the provision of the through-hole 74 improves the heat dissipation property of the second component 22. That is, the second component 22 is easily cooled by the through-hole 74. Thus, even if the nameplate 60 is attached to the outer surface 22d of the second component 22, the adhesive layer 61 can be stably held. Therefore, while efficiently cooling the second component 22, the reliability of attaching the nameplate 60 can be improved.

[0054] [Modification Example] Note that each of the above embodiments can be modified as follows. Each of the above embodiments and the following modification examples can be implemented in combination with each other within a technically non-conflicting range.

[0055] ○ In the second embodiment, depending on the arrangement of the nameplate 60 on the outer surface 22d, the through-hole 74 may be changed to be provided in the first cover 71. Also, depending on the arrangement of the nameplate 60 on the outer surface 22d, the through-hole 74 may be arranged to straddle the boundary between the first cover 71 and the second cover 72.

[0056] ○ In the second embodiment, the nameplate 60 may be provided on the outer peripheral surface 22c of the peripheral wall 22b of the second component 22. When modified in this way, the through-hole 74 may be provided in the first cover 71 or the second cover 72, or may be arranged to straddle the boundary between the first cover 71 and the second cover 72. That is, in the second embodiment, the nameplate 60 may be provided on the second outer surface corresponding to the discharge portion of the outer surface 20a.

[0057] ○ In the first embodiment, depending on the arrangement of the nameplate 60 on the second surface 23b, the through-hole 73 may be changed to be provided only in the first cover 71 or the second cover 72. ○ In the first embodiment, the nameplate 60 may be provided on either the third surface 23c or the exposed surface 23d. When changing in this way, the through-hole 73 may be provided on the first cover 71 or the second cover 72, or may be arranged so as to straddle the boundary between the first cover 71 and the second cover 72. That is, in the first embodiment, the nameplate 60 only needs to be provided on the first outer surface corresponding to the inverter accommodation part of the outer surface 20a.

[0058] ○ In each of the above embodiments, one nameplate 60 is arranged, but a plurality of nameplates 60 may be arranged. In the first embodiment, when two or more nameplates 60 are arranged, each nameplate 60 may be appropriately provided on the second surface 23b, the third surface 23c, and the exposed surface 23d. And it is preferable that the soundproof cover 70 is provided with the same number of through-holes 73 as the number of nameplates 60.

[0059] In the second embodiment, when two or more nameplates 60 are arranged, each nameplate 60 may be appropriately provided on the outer peripheral surface 22c and the outer surface 22d. And it is preferable that the soundproof cover 70 is provided with the same number of through-holes 74 as the number of nameplates 60. Note that the number of the through-holes 73 and 74 is preferably set to a number that does not significantly reduce the noise reduction effect of the soundproof cover 70.

[0060] ○ In each of the above embodiments, when a plurality of nameplates 60 are arranged, each nameplate 60 may be provided on any one of the second surface 23b, the third surface 23c, and the exposed surface 23d, and may also be provided on any one of the outer peripheral surface 22c and the outer surface 22d. For example, when two nameplates 60 are arranged, it may be changed such that one nameplate 60 is provided on the second surface 23b and the remaining nameplate 60 is provided on the outer surface 22d. That is, the nameplate 60 only needs to be provided on at least one of the first outer surface corresponding to the inverter accommodation part and the second outer surface corresponding to the discharge part of the outer surface 20a. Note that in this specification, "at least one of the first outer surface and the second outer surface" includes the meanings of "only the first outer surface", "only the second outer surface", and "the first outer surface and the second outer surface".

[0061] ○ In each of the above embodiments, the nameplate 60 is a seal, but it may be, for example, a metal plate. When the nameplate 60 is a metal plate, the nameplate 60 may be fixed to the housing 20 using a fixing member such as a bolt. When the nameplate 60 is fixed by a fixing member, the adhesive layer 61 may be omitted.

[0062] ○ In each of the above embodiments, the nameplate 60 is not limited to a rectangular shape, and the shape may be changed as appropriate. Note that, as the shape of the nameplate 60 is changed, the shapes of the through portions 73 and 74 may be made to conform to the outer edge of the nameplate 60.

[0063] ○ In each of the above embodiments, the through portions 73 and 74 do not have to be shaped along the outer edge of the nameplate 60. For example, when the nameplate 60 is viewed from the front in its thickness direction, the through portions 73 and 74 may be circular. Even if changed in this way, the nameplate 60 may be surrounded by the through portions 73 and 74.

[0064] ○ In each of the above embodiments, the through portions 73 and 74 do not have to surround the nameplate 60. In other words, the through portions 73 and 74 may be smaller than the size of the nameplate 60. When changed in this way, the through portions 73 and 74 should be sized such that the predetermined information 62 described on the nameplate 60 is visible.

[0065] ○ In each of the above embodiments, the first component 21 and the third component 23 may be integrally formed. In this case, the exposed surface 23d is a surface that is integrally continuous with the outer peripheral surface 21c of the peripheral wall 21b.

[0066] ○ In each of the above embodiments, the third component 23 is not limited to a shape that protrudes more than the first component 21 in the radial direction B. For example, it may be changed such that the entire area of the first surface 23a of the third component 23 contacts the end wall 21a of the first component 21. That is, the exposed surface 23d may not be included in the first surface 23a. When changed in this way, the first outer surface of the portion of the outer surface 20a corresponding to the inverter accommodation portion is the second surface 23b and the third surface 23c.

[0067] ○ In each of the above embodiments, the compression unit 30 is not limited to a scroll type, and may be, for example, a piston type, a vane type, or the like. ○ In each of the above embodiments, the soundproof cover 70 has the first cover 71 and the second cover 72, but may be composed of three or more covers.

[0068] ○ In each of the above embodiments, the soundproof cover 70 may be formed of any material as long as it has a soundproof function. The soundproof cover 70 is not limited to a resin material such as a urethane material, and may be formed of a non-woven fabric or the like. Further, the soundproof cover 70 may be configured in a two-layer structure or a three-layer structure or more, such as being formed of urethane on the inside and a resin material other than urethane on the outside.
